APPLICATIONSLEMD liquid ring vacuum pumps are displacement single-stage pumps to handling and exhausting of dry and humid gases, entrained liquid can be handled during normal duty.
Benefits
Non-polluting due to nearly isothermal compression
Oil-free, as no lubrication in the working chamber
Handling of gases and vapours
Small quantities of entrained liquid can be handled
Easy maintenance and reliable operation Low noise and nearly free from vibration
Incorporated central drain
No metallic contact of the rotating parts
Shaft seals
The LKH Prime is equipped with either an external single or a double mechanical shaft seal. Both have stationary seal rings made from stainless steel AISI 329 with sealing surface in silicon carbide and rotating seal rings in carbon as standard.
